Short period

Maria

I have PCOS and normally will go a few months with no period. Well my period started 2 days ago but was super light and barely anything at all and I had cramps so I thought “this is the beginning” I barely filled one pad. Woke up today and it’s basically gone and the cramping is gone as well. Does anyone know anything about PCOS and having short period because typically mine last 7-9 days and are super heavy. Especially after missing them for a couple months.
